How to Use This Manual
The MERLINm communications system provides you with features that give your
business many expanded communications capabilities. Each voice terminal
(MERLIN system telephone) comes with features already assigned that allow you
to transfer calls, put people on hold, and setup conference calls. You can program
other features onto the system and onto individual voice terminals, such as one-touch
dialing of outside or intercom numbers or one-touch redialing of a number you have
saved.
As system administrator, you are responsible for making the
MERLIN system work
to its maximum efficiency in serving your company’s communications needs. You
need to know more about its custom features, capabilities, and programming than
does the average telephone user. This administration manual gives you the infor-
mation you need to setup and customize your MERLIN system. Here is how to use
this manual:
1. Read “Setting the Control Unit," pages 4-5, to become more familiar with
the lights and switches on the control unit. To set your control unit for use,
follow the procedures described on page 4.
2. Read “Reviewing Your MERLIN System’s Fixed Features," pages 6-7, and
become familiar with the MERLIN system fixed features, those features
that are already available when your system is installed.
3. Look at “Selecting and Programming Custom Features," pages 8-13, and
decide which custom features best meet your business’ and the individual
user’s needs. Then, do the necessary programming by following the “Basic
Programming Instructions” on page 10.
4. If you have an attendant, review “Special Information for the System At-
tendant,” pages 14-15, and be sure that he or she knows the steps for
assigning line ringing options, transferring calls, and using Intercom Auto
Dial buttons and a headset.
5. In case you ever need to relocate or you decide to purchase more equip-
ment for your system, look over “Moves and Changes,” pages 16-17.
6. If your system malfunctions, refer to “Isolating and Correcting Troubles,"
pages 18-19.

Setting the Control Unit
Your MERLIN system control unit connects lines from the telephone company and the individual voice terminals in your
business. The software in its cartridges lets you program features, and it can accommodate optional cartridges that pro-
vide still more features. Model 206 has two outside line jacks and six voice terminal jacks; Model 410 has four outside
line jacks and ten voice terminal jacks.
Read the following descriptions of the parts of the control unit, and study the diagram on the next page. When you are
ready to begin to set your control unit, complete the necessary steps described in “Setting the Switches,” below.

Selecting and Programming Custom Features
With the MERLIN system it is possible to assign and reassign programmable features to available buttons on the voice
terminal. (See “Initial Feature Assignments,” page 9.) Thus, people in your telephone system can customize their voice
terminals by selecting the custom features that best suit their individual needs. (See the chart below.) However, some
of these features, such as Automatic Line Selection and Programmable Line Ringing, have a broader application because
they influence the calling patterns of your business. Because these features have businesswide impact, you may want
to oversee their assignment.
Uses and Benefits of Custom Features

INITIAL FEATURE ASSIGNMENTS
When your MERLIN communications system voice terminals are first installed, they
have the features shown below. If the individual voice terminal users want to program
different custom features onto these buttons than those already assigned to their
voice terminals, they can choose custom features from the chart on page 8. Other-
wise, the buttons can remain with the initially assigned custom features. Note that
you cannot change the outside line and the intercom line buttons. Those people who
have 5-button voice terminals connected to the Model 410 control unit should be
aware that their voice terminals have four line buttons and an intercom button rather
than programmable buttons.

Programming Tips
● If the person has a Hands-Free Unit, program Auto Answer-Intercom on a button.
● Have the user decide which people within your business he or she will frequently
call, and program an Intercom Auto Dial button for each of those people.
● Make all remaining buttons Outside Auto Dial buttons and program them for
frequently called outside numbers.
● Decide if the person using this voice terminal will cover calls for anyone, and
then program the appropriate line ringing options. (See “Programming Line
Ringing Options," page 12.)
Before you begin programming, check the Feature Programming Chart on page 11
for programming details for each custom feature. Be especially aware of which
custom features need buttons with lights. When you complete the programming pro-
cedure, keep this chart handy as a quick reference in case you want to reassign a
new feature onto an available button.
Special Characters in Programming Outside Auto Dial
You may need to include some special characters, such as a pause, a stop, or a
switchhook flash, when you program outside telephone numbers, PBX or Centrex
feature codes, an alternate long distance number, or other computer services onto
an Outside Auto Dial button.
Pause. To program a 1.5 second pause into a dialing sequence: touch Hold
(Pause).

PROGRAMMING LINE RINGING OPTIONS
You can program how and when incoming calls ring on each outside line at each
voice terminal. When your system is installed, the lines at each voice terminal ring
immediately when a call comes in on them. However, you can change this by pro-
gramming some lines to ring at one voice terminal, other lines at Other voice terminals,
or the same line to ring differently at different voice terminals. You can even have
a line ring at one voice terminal only if it is not answered at another after a designated
number of rings. Read the following tips on how you can program this feature.
● Immediate Ring. People responsible for answering incoming calls, such as the
system attendant, should have the lines on their telephones programmed for
immediate ring. (See “Special Information for the System Attendant,” pages
14-15.) You can also use this option for private lines that don’t need to be screened
or for people who answer their own calls.
● Delayed Ring. You can provide backup coverage on a shared line by having
that line ring at a second voice terminal only after it has rung a few times
somewhere else. Then, when calls come in for a person who is away from his
or her desk, that person’s calls will ring at a second telephone, the voice ter-
minal of a backup person. Delayed ring is often useful for a secretary who can
pick up calls for someone on a private line.
● No Ring. People who do not normally answer incoming calls should have their
lines programmed to no ring. Also, you might program telephones in public
places, such as lobbies or conference rooms, not to ring. A line programmed
to no ring does not ring on outside calls, but continues to ring for transferred
and intercom calls.
To program the type of line ringing you want, follow these steps:
1. Slide the T/P switch to F!
2. Touch the line buttons successively until the red light indicates the type of
ringing you want:
Red light on
= immediate ring
Red light flashing = delayed ring
Red light off = no ring
3. Slide the T/P switch to the center position.
ASSIGNING AUTOMATIC LINE SELECTION SEQUENCES
Automatic Line Selection determines which free line the system gives each voice
terminal when someone lifts the handset to make a call. When your system is
installed, the system selects free lines appearing on voice terminal line buttons in
the order in which the lines are plugged into the control unit jacks. This means that
if line A, which is plugged into jack A on the control unit, is busy when you pickup
the handset, the system automatically gives you line B, plugged into jack B. The in-
12

itial Automatic Line Selection order for voice terminals plugged into the Model 206
control unit and those plugged into the Model 410 control unit appears below.
Line D
Line C
MODEL
410 Line B
MODEL
206
Line A
However, a different order for the Automatic Line Selection maybe more efficient
for your voice terminals. For example, you may want to make the least-used line the
first line to be selected in the line sequence. All, some, or none of a voice terminal’s
lines can be placed in an Automatic Line Selection sequence, and the sequence can
be different for each voice terminal. Below are some tips to guide you in assigning
Automatic Line Selection sequences.
●
●
●
●
●
If all lines are regular telephone company lines, you probably won’t want to pro-
gram this feature. In this case, the system selects the lines in the order in which
they are plugged into the control unit jacks.
You may want to reserve your published telephone number for incoming calls
and therefore place it last in the line sequence on everyone’s voice terminal.
It is usually not a good practice to have different types of lines programmed into
the same Automatic Line Selection sequence. If, for instance, you have an FX
line to a specific location included in the sequence, do not also include a regular
line which could be used to call anywhere. Also, if you use FX lines, make cer-
tain that all of these lines you program into an Automatic Line Selection se-
quence go to the same place.
If a person in the office places mainly long distance calls, program the Automatic
Line Selection sequence to first select the WATS lines and then select regular
lines that allow callers to make both local and long distance calls.
Since usually the line you specify as first in the sequence gets the most use,
it maybe to your advantage to spread telephone usage evenly across your lines,
especially if you have usage-sensitive rates on your local telephone lines. You
can accomplish this by assigning different people different sequences for
Automatic Line Selection.
To program Automatic Line Selection:
1. Slide the T/P switch to P.
2. Dial **.
3. Touch the line buttons in the order you want them to be selected.
4. Slide the T/P switch to the center position.

Special Information For The System
Attendant
Many businesses have a system attendant or receptionist, a person who answers
the calls and transfers them to other people in the office. If your business has an at-
tendant, you will want to make sure that he or she reads and understands the following
information about assigning line ringing options, transferring calls, and using Inter-
com Auto Dial buttons and a headset.
ASSIGNING LINE RINGING
You and the attendant can determine whether incoming calls on the voice terminals
ring immediately, ring after a delay, or do not ring at all. The programming procedure
is so simple that you can change call coverage and line ringing on an as-needed
basis. If the attendant answers most of the calls that come into the office, you may
find it best to program lines on other phones either to delayed ring or no ring. (Also,
see “Programming Line Ringing Options,” page 12.) Here are some tips for the
attendant:
● If there is no backup for the attendant when he or she is unavailable, set the
lines on all other phones in the office to delayed ring, so that if the attendant
is unable to answer incoming calls (after two rings), the calls automatically ring
at the other voice terminals in the office.
● If there is someone to cover for the attendant, calls should be routed to that per-
son rather than ringing at other voice terminals in the office. Program the backup
person’s lines to delayed ring and program all others in the office to no ring.
● If the usual backup person is unavailable, simply reprogram his or her lines to
no ring and program someone else’s voice terminal to delayed ring for the time
that the attendant and the backup person are away.
TRANSFERRING CALLS
If the attendant answers most of the incoming calls, he or she should be familiar with
the three ways to transfer calls: directly, with intercom announcement, and with Hold
and intercom consultation.
Transferring Calls Directly
Transferring a call directly to someone else, without intercom announcement or con-
sultation, is very simple:
1. Touch Transfer.
2. Touch the Intercom Auto Dial button or dial the intercom number of the person
to whom the call is being transferred.
3. Hang up.
The person to whom the call is transferred hears a distinctive transfer ringing and
lifts the handset. If no one answers the call, it returns to the attendant’s phone.
14

Transferring Calls with Intercom Announcement
With an extra step, the person to whom the call is transferred can be toId who is
calling:
1. Touch Transfer.
2. Touch Intercom.
3. Touch the Intercom Auto Dial button or dial the intercom number of the person
to whom the call is being transferred.
4. Make your announcement.
5. Hang up.
The person receiving the transferred call hears the announcement over the voice
terminal speaker and needs only to lift the handset to accept the call.
Transferring Calls with Hold and Intercom Consultation
With this method the attendant is able to discuss the call with the person to whom
it is being transferred. There are many reasons for consulting about the call: a per-
son may want to get out a file before taking the call, maybe busy and not want to
answer the call at all, or may want the attendant to answer the call and take a
message.
1. Touch Hold.
2. Touch Intercom.
3. Touch the Intercom Auto Dial button or dial the intercom number of the person
to whom the call is being transferred.
4. Discuss the call with the person.
5. Tell the person on which line to pick up the call.
6. Hang up.
USING INTERCOM AUTO DIAL BUTTONS
For the attendant, programmed Intercom Auto Dial buttons increase the efficiency
of the Transfer feature in several ways:
● It is easier and quicker to make intercom calls.
● The green light next to the button shows when a line is busy (steady light).
● The green light also identifies the person calling the attendant (rapidly flashing
light).
USING THE HEADSET
If the attendant has a heavy call-handling load, he or she may want to use a headset
with the Headset Adapter rather than lifting the handset throughout the day.
15

Moves and Changes
Your MERLIN system can expand as your company grows and as your communica-
tion needs increase. It is simple to increase its capacity, and since the system is
modular in design, you can add features and accessories. In addition, every com-
ponent in the MERLIN system is portable, so if your business moves, your MERLIN
system can move with you.
MOVING YOUR SYSTEM
If your business moves, just take the MERLIN system with you. All the connecting
cords are snap-in, modular, and easy to install. You need to order new lines from your
local telephone company and, depending on your new floor plan, you may need to
order some new lengths of modular connecting cords from your
MERLIN system
supplier.
If you relocate people within your business, they can keep the same voice terminals,
intercom numbers, and all programmed features. Simply move the voice terminals
to the new offices, then connect the voice terminal cords to the control unit.
To keep
the same features, each voice terminal must keep the same intercom number. (For
more information on moving your system, refer to the Installation Guide: Models 206
and 410.)
INCREASING YOUR SYSTEM’S CAPACITY
There are several ways in which you can make additions to your system:
● You can order another line from the telephone company; all you need from your
MERLIN system supplier is another modular line cord.
● You can purchase additional voice terminals and appropriate-length extension
cords and plug them in yourself.
● If your business communications needs outgrow the capacity of your present
MERLIN system, you can replace the control unit with a larger model. But, you
can keep and continue to use your voice terminals, feature cartridges (unless
you purchase a Model 1030 control unit), and accessories.
ADDING FEATURES AND ACCESSORIES TO YOUR SYSTEM
Although you need only the control unit and the individual voice terminals to setup
and use your system, you may also have optional equipment that adds features and
capabilities to your system. Note that optional features often require the purchase
of additional equipment.
By purchasing one or more of the following cartridges, you can increase the
usefulness and flexibility of your MERLIN system:
● Another Feature Package (Type 1 cartridge) adds custom features to your system,
thus expanding the operation of each voice terminal.
● An audio cartridge (Type II cartridge) enables you to add to your system such
features as Music-on-Hold, which provides music for clients whom you put on
hold, and Loudspeaker Page, which allows you to use a loudspeaker system.
● An added-services cartridge (Type ill cartridge) allows you to add Extra Alert
horns or bells so workers in noisy areas of the building are aware that the
telephone is ringing, and Power Failure Transfer telephones which continue ser-
vice in case of loss of electric power.
The chart on page 17 lists the optional features, any required equipment, and the
uses and benefits of each feature.
